Title:
DOWNLINK CONTROL INFORMATION DESIGN FOR SUPPORTING SINGLE DCI SCHEDULING FOR MULTIPLE CELLS
Document Type and Number:
WIPO Patent Application WO/2023/206208
Kind Code:
A1
Abstract:
A single Data Control Information (DCI) may be used to schedule physical data channels, e.g., PDSCH/PUSCH, for a given device/user equipment (UE) on multiple cells. Accordingly, a single DCI may be transmitted to a device/UE to schedule physical data channels on multiple cells for the device/UE, for example to concurrently schedule the physical data channels for the device on multiple cells/component carriers. The single DCI may include multiple DCI fields for indicating required communication parameters. Each DCI field of at least a subset of the multiple DCI fields is either used for every cell of the multiple cells or for a corresponding single cell of the multiple cells. Whether a single DCI field or multiple DCI fields are used for a given relevant communication parameter may be determined individually for each of the relevant communication parameters which are to be indicated in the single DCI.
